Aeroplanes,--f which the following is a "ability-to rise vertically, and in the case of specification.

' My invention relates to an improvement in aeroplanes and has for its primary object 'the construction of a simple, durable and inexpensive device capable of rising verti;

cally from the-ground.

Still another object of my invention is to provide a device of the class described with mishap to machinery the rising propeller will seal itself by the releaseof a rope and act as a parachute.

Still another object of my invention is to provide an aeroplane with a propeller for vertical rising, and the said propeller being adjustable with regard to the angle by which it cuts the air, having a device which will hold the blades in angular position should any mishap occur in the machinery or the driving device or the means by which the propeller is held at an angle. lhe said propellers will automatically flatten out and form a parachute.

These and such other objects as may be here-in-after enumerated are attained by the novel construction; combination and arrangement of parts to be hereinafter specifically referred to and claimed.

Though I show one particular embodi ment of my invention, I wish to be limited only to the scope of my claims as it will readily be seen that mere mechanical details may be changed without going beyon the limitation of my claims.

Reference will now be had to theaccompanying drawings forming a part of this application. Figure (1) is. a plan view showing the vertical propeller frame work, horizontal propeller, and rudder. Figure (2) is an enlarged view showing the mechanism controlling the angle at which the propeller is to be operated. This view is broken and is an isometric view. Figure (3) is a side elevation of the aeroplane, on section 33 showing driving mechanism and other parts which can not be clearly shown otherwise.

Throughout the following detailed description and on these several figures of Specification of letters Patent. 3 Patented Jam; 3, 1922. Application filed March 1, i

drawings similar parts are referred to by l1ke reference characters. Numerals (1) are a plurality of propeller blades made up ofcloth and stretched over a propeller frame (2) which is covered by a fabric 2 which rotates about the shaft'(3) which acts as a shift only with regardto the angle. The propeller blades are set. The ni ger head (4) revolves about a shaft (5). he ni er head is driven by a rope (6) w lch travels over a pair of shift wheels (7), located in the main frame (8) of the propeller .mechanism. The rope (6) receives its energy from a drive shaft (9) which may be connected to an energy producing mechanism such as a gasolene motor or an electric motor or the like.

At one end of each of the propeller blades (2) is a shift pin (10), which is revolvably fixed in a lug (l1), and the lug (11) bein rigidly fixed inan angle iron hoop (12 and at the opposite end of the propeller frame (2) is another shift pin (13) which is revolvabl held by lug (14:), which in turn is ri-gi ly fixed to an angle iron hoop (15). It will be seen: that by a pull on rope .-(16) exercising its "energy or lever (18) that, through a dog (19) the power exerted on (16) wlll, draw hoop (15) away from hoop (12), thereby regulating the angle at which these propeller blades are set at the choice of the operator. Lever (18) is pivoted on a bolt or pin (20)= which is rigidly fixed to frame (8). From this description it will also be seen that should some mishap occur in the machinery or the rope, or cable should break the descending of the plane would force the propeller blades to close up and form a form of parachute, as the upper hoop (12) could not raise by the pressure of the wind against a roller (21) which is revolvably fixed in place on the stationary 'frame (8) by the propellerrblades being pivoted. in themselves of]? center on their shafts (3) the pressure would raise the end connected to the hoop (15). This wouldmove up close enough to form the outer rim of a parachute and retard the descending of the L 105 plane. (22) is a propeller which causes the horizontal movement of the plane and is (27). This cable or rope receives its energy from a drive shaft (28) which in return is driven by some form of motor power similar to that driving the drive at (9) and which is located in the body of the plane (29). (30) are the truss rods which are used to stiffen the frame and (31) are the brace rods which hold the frame in its proper position. (32) is the rudder of usual type and controlled by mechanism of convenient design. (33) are roller bearings set in nigger head (4) which revolve about the strut shaft (34) which is .a part of the frame work (8) nd the body of the plane (29).

{Having thus described my invention or what I claim is new and desire to protect by Letters Patent is:

In an aeroplane, of the class described a propeller for horizontal motion of the aero- 4 plane and controllable propeller for vertical motion, this propeller consisting of a plurality of blades each rotatably mounted on a shaft, the inner end of the shaft rotatably mounted on a spindle of a vertical shaft, the outer end of the shaft rigidly affixed to propeller blade frame 2, two outer rim rings, means for attaching said frame to said outer rim rings, and means for governing the distance of separation of said rim rings, to govern the set or angle of theblades and a means for driving the vertical shaft which imparts the motion of the propeller, and a frame of suitable construction for molding all the above said means in place.

In testimony whereof, I have affixed my signature in the presence of two witnesses.
